erm, yes.
i want a highlighter pen type function. i want to be able to highlight the important parts of an article etc so when i come back to a pdf i can go straight to the important reason i pdf'ed the article in the first place.
i hope there is a free app because the one i remember seeing was $50 or something... too much in my opinion for this simple function. anyway, ive spent too much on apps over the years and i probably dont use 75% of them anymore.
